Sample selection for the analysis reported in the main text of 
"Marital matching, economies of scale and intrahousehold allocations"
by Laurens Cherchye, Bram De Rock, Khushboo Surana and Frederic Vermeulen
===========================================================================

* '2013raw' contains the raw data file of 9063 household. This data file is already merged with the annual consumption expenditure of the households. Both the datafiles can be downloaded in the original form from the PSID website (https://psidonline.isr.umich.edu/) using files '2013 Main Study Family Files' and 'Consumption Expenditure Data'. Note that this dataset contains more than 5000 variables, so before opening the dataset in stata, one needs to increase the number of variables that can be used in stata (use command: set maxvar 32000)

* 'code cleaning_onlycouples' is the stata do-file which can be used to obtain the sample of couples selected for the analysis in the main text. It takes as input the '2013raw' dataset and outputs the 'psid_cleaned_onlycouples' dataset containg observations of 1322 couples.
